Truth: A Love Story
Only now do I realize that my mother, my angel and protector, 11 years younger than my father, also excelled at this, and I suspect I learned a great deal from her, albeit subliminally. This remarkable fact of inheritance provides a foundation for relating the amount of DNA identity between any two persons and the number of generations likely separating their last common ancestors—parents for siblings; grandparents for cousins; great-grandparents for second cousins; etc. Within two months of searching public and private DNA ancestry databases, identifying DNA relatives and the amount of DNA identity, and computing, constructing, and connecting family trees up and down multiple generations, I eventually discovered the identity of my biological father, whom I had code-named “the crybaby” since my latent but previously suppressed ability to cry had been fully unleashed during this period.
